Google Calendar will stop supporting SMS notifications on June 27

Google Calendar SMS notifications are going the way of Google Reader, Google Wave, and Knol. On June 27, users of the tech giant’s calendar platform who currently utilize the text message reminder feature will have to transition to relying on smartphone notifications.

The Google Calendar help page dedicated to SMS notifications has a prominent notice at the top warning users that SMS notifications won’t be available starting on June 27.

“SMS notifications launched before smartphones were available,” according to the Google Calendar help page. “Now, in a world with smartphones and notifications, you can get richer, more reliable experiences on your mobile device, even offline.”

Google suggests two alternatives: Use the calendar app that came with your smartphone, or install the Google Calendar app for your Android or iOS device. Those who don’t own smartphones are left out to dry when it comes to getting reminders from Google Calendar.
